Many calls from this number. Who is the owner?

Agree....very hostile and harrassing.

It's a debt collector.

Recieved many calls from this number on Caller ID, when we attempted to call back - the person on the other line was rude stating that "if we didnt know how to speak proper english we shouldnt be calling places." then abruptly hung up. I found that extremely offensive and i would like to report this person's unprofessional and rude behavior.
